Additional Tech Info

The driver normally operates using the standard 11 bit PPI protocol. If the use of the EM 241 modem module is required, the S7-200 PPM model must be selected. The S7-200 PPM model allows the driver to operate in a 10 bit mode, which is more compatible with a wide range of off-the-shelf modems. The 10 bit PPM mode can also be used directly on the PLC's programming port. To enable the 10 bit PPM mode, set the S7-200 programming cable 10 bit mode.
